About our steel goalpost frames service in Portishead
We cover steel goalpost frames in Portishead (BS20) and the streets around it. The wider Somerset area is covered as well. Each job is designed by a structural engineer and approved through North Somerset Council before work begins.
When a rear wall is opened almost corner to corner, or the brickwork either side is too thin, cracked or broken up by openings to take a concentrated load, a beam on padstones is not enough. A goalpost frame brings its own supports: two columns carry the beam's ends straight down to new foundations, so the walls around the opening are not relied on.
Worth knowing before you start
- A goalpost frame usually takes longer than a single beam because the pads need digging, inspecting, pouring and time to gain strength before the columns take load. The engineer sets when the frame can be loaded.
- Stability is part of the design, not just strength. A frame standing in a wide opening can sway sideways if the joints are too flexible, so the engineer decides whether the connections must be moment-resisting or whether the frame is tied back to the surrounding structure.
- In older homes with suspended timber ground floors, the column has to pass through the void to reach the pad. Air bricks, joists and the damp-proof course around each column are considered so ventilation and damp protection are not compromised.
- Columns are commonly universal columns or square hollow sections, welded to steel base plates at the foot and cap plates at the head. Holding-down bolts fix the base plates to the pad, and grout fills the gap beneath once the frame is level.
- Goalpost frames are made to measure, so accurate site dimensions matter. Floor-to-ceiling height, the finished floor level and the width between column positions are taken before fabrication, because a frame that is a few millimetres out cannot simply be trimmed on site.
Four stages, one team
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to North Somerset Council, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building control and neighbours in Portishead
For Portishead, building control is provided by North Somerset Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Steel goalpost frames in Portishead: your questions
Do you also work near Portishead?
Yes. We also cover nearby towns including Nailsea, Clevedon, Kingswood and Mangotsfield.
Who approves steel goalpost frames in Portishead?
Structural work in Portishead needs a building notice or full plans application to North Somerset Council or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
When do you need a goalpost instead of a steel beam?
You need a goalpost when the walls at either end of the opening cannot safely carry the beam. That happens when piers are too narrow, the masonry is weak or cracked, the opening runs almost wall to wall, or the footings below are unsuitable. The structural engineer makes the call after looking at the loads and the bearings available.
How long does it take to install a steel goalpost?
Allow around one to two weeks on site for a typical job. Breaking out and digging the pads, the foundation inspection, pouring concrete and letting it gain strength take up much of that time. Erecting and bolting the frame itself is often done in a day, followed by inspection and boxing in.
Can a goalpost frame be hidden?
Usually, yes. The columns can be boxed in with fire-rated plasterboard so they read as small piers, set inside new walls, or hidden within the line of an extension's side walls. The beam is boxed like any other steel. Some owners prefer to leave the frame exposed and painted as a design feature.
What happens at the survey visit in Portishead?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
